CLANG!!!
The enormous sphere of Planetary Devastation settled onto the ground in Amegakure.
Whoosh!
Naruto flashed out of Flying Thunder God and told the stunned onlookers, "I brought Kumogakure's Hell Valley over..."
Konan asked, "What suddenly made you decide to bring it here?"
Naruto said, "Ever since I last left Hell Valley, I haven't properly trained my Purple Electricity Chakra Mode. There's actually still plenty of room for improvement, so I'll take this opportunity to really hone it!"
Shikaku had already returned to Konoha. Before leaving, he had given Naruto a warning.
"Obito has no way out anymore. Now that he's discovered his weakness, he'll do everything he can to overcome it. By the time you actually fight, even your shadow tactics might not work. So, Naruto, don't count on having a fallback either. If there's anything you can improve, improve it now!"

Planetary Devastation peeled away like an eggshell, and Hell Valley became one of Amegakure's facilities!
"Konan, unless something earth-shattering happens, tell everyone not to interrupt my training..."
Whoosh! His robes billowing, Naruto strode toward Hell Valley!
"I'm going to pound Obito into a pulp..."
And so, Naruto began another round of hellish training!
Ryūchi Cave, Back Mountain.
In a single day and night, Madara mastered Ryūchi Cave's Frenzy Sage Technique!
Nine Sage Snakes coiled around Madara's body!
"So this is all Ryūchi Cave's Senjutsu amounts to..."
Whoosh! Whoosh!
The Sage Snakes withdrew, and the horns that had appeared on Hashirama's forehead on Madara's chest retracted as well.
Rustle, rustle, rustle...!
Black Zetsu emerged from the ground.
"Congratulations on another triumph, Lord Madara. Now
